I don't know if this is Prada. I'm sure someone would have pointed it out if it were. So much for the "no witch" policy - this almost counts as number two... (and she's brilliant as both).
*In case you're not familiar with either reference, the lines are from Into The Woods, the footage from The Devil Wears Prada, in which Emily Blunt played the harried first assistant to a powerful (and scary) fashion magazine mogul, played by Meryl Streep. It fits so well it's both hilarious and eerie.
